Ubuntu grafana服务器在CHDIR步骤失败

我在我的

ubuntu16.04

机器上安装了

grafana

，正如它在其；然后我执行了以下操作：

zeinab@ZiZi:~$ sudo systemctl daemon-reload
zeinab@ZiZi:~$ sudo systemctl stop grafana-server
zeinab@ZiZi:~$ sudo systemctl start grafana-server
zeinab@ZiZi:~$ sudo systemctl enable grafana-server

但是

sudonetstat-plntua | grep3000

什么也不返回。我没有对配置进行任何更改。在

/var/log/grafana/grafana.log

中没有写入任何内容，但是在执行上述命令的过程中，我在

/var/log/syslog

上看到了

grafana

的以下几行内容：

Feb 15 15:11:38 ZiZi systemd[1]: Stopped Starts and stops a single grafana instance on this system.
Feb 15 15:11:44 ZiZi systemd[1902]: grafana-server.service: Failed at step CHDIR spawning /usr/sbin/grafana-server: No such file or directory
Feb 15 15:11:44 ZiZi systemd[1]: Started Starts and stops a single grafana instance on this system.

Feb 15 15:11:44 ZiZi systemd[1]: grafana-server.service: Failed with result 'exit-code'.

原因是什么？我做错什么了吗？是否与安装过程有关

编辑1:

以下是sudo systemctl status grafana服务器返回的内容：
